According to Newton's 3rd Law of Motion, when a tennis ball hits and exerts a force on the ground, the ground

moves away from the egg
Ann rolled a heavy bowling ball down the lane. The ball gradually slowed down and stopped. Why did the bowling ball stop moving?
The lane absorbs force from the bowling ball.
The lane exerted a force that is opposite to the direction of the bowling ball's motion.
The bowling ball ran out of force.
All objects stop moving because their natural state is to be still.
Mark all of the types of friction.
sliding friction
rolling friction
fluid friction
gravity

Stop pushing
Push with the same amount of force that you have been using
Push with less force
Push with more force
A small car with a mass of 1000 kg collides with a bus with a mass of 8000 kg. Which will have the most force?

when two unequal forces act in opposite directions on a moving object, the object will
absorb the force
come to an immediate stop
continue to move in the same direction
move in the same direction as the larger force
An object is placed on a surface and starts to slide. What is the most likely reason that the object starts to move?
Gravity is exerting a balanced force on the object.
Gravity is exerting an unbalanced force on the object.
Friction is causing the object to move.
The forces acting on the object are in equilibrium.
If you reduce the mass of an object
it will have greater gravitational force.
it will use more energy to make it move.
It will take less force to make it move.
